In the opening, the van carrying the prisoners is a Sheriff's Dept. van. The guards are wearing California Dept. of Corrections uniforms, which is a state agency.
Just before the truck hits the prison van, the close-up of the front of the truck is flipped; the license plate and the "Ford" nameplate are backwards.
Where did Caitlin get all boxes of personal possessions to pack up? Just three episodes earlier she lost everything she owned when a moving truck carrying all her packed possessions was blown up and then burned in the subsequent fire.
